I'm happily flying around the FSX world in David's Comet 4 and it's pleasing to report that all the gauges transfer from FS9 and behave well.
Except one - the Mach meter is reading way too high.
I've tried switching the VC10 gauge in but with exactly the same result.
I presume they must now be reading a different parameter or calculating in a different way.
Any experts out there who might understand the reason?
